Video input card for a laptop

[OCCSteve]

Does anyone know of a external card with a BNC input that will allow a laptop to be used as a test monitor for a standard NTSC video format on a CCTV system.
I help maintain our camera system. At my old job we had small testing monitors for focusing cameras, but I'm just wondering if there is a cost effective alternative that would allow the use of a laptop I already have.

Thanks.

something like this along with an adapter from BNC to CINCH or SVideo...

Nothing I could find was cheaper than a $99 LCD monitor...unless you do as Ben suggests and use an adapter. If it's just one camera system you're monitoring I would think a dedicated display would be more convenient anyway.

What I'm looking for is a cheap way to use my small laptop as a focusing monitor, rather than spend the money on an actual test monitor. There are actually about 75 cameras & it's easier to focus a fixed camera locally than it is to try & have someone at the head-end communicating adjustments to you. I think something like what Ben suggested will work, but I'm going to look around a little more.

Thanks guys.
